PILOT-LIGHT VALVE.

Specification of Letters Patent. Patntd un@ 20 1911.

Application led November 17, 1909.` Serial No. 528,490.

To all whom 'it may concern:

Be it known that I, LAURENCE P. Diener, a citizen ofthe United States,and a resident of Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented certain new and useful Improvements inPilot-Light Valves, of which the following is a speciiication, referencebeing had to the accompanying drawings.

This invention relates to valves having a by-pass for the passage of aminimum supply of illuminant to maintain a small jet burning while theilluminating burner valve is turned off, for the purpose of igniting thesupply of illuminant ejected from said burner when the burner valve isopened.

The principal objects of this invention are, to provide a valve arrangedto insure the ignition of illuminant when turned on, with an enlargedequalizing chamber from which the illuminant is distributed through theconduits to the burners;- to provide a tapering rotary controlling valveplug, normally maintained seated by gravity and opening into saidenlarged chamber in the valve casing; to provide said casing with meansarranged to support a plurality of conduits eontemporaneously controlledby said valve plug, and provided with passage- Ways in communicationwith said chamber independent of said valve plug; to provide meanswhereby said communication may be readily eiiected; and to provide avalve structure readily taken apart to aord access to the parts closedby the valve casing, and to the passageways extending through saidcasing.

This invention is further advantageous in that it provides meansarranged to close communication through said passageways by shiftingsaid conduit, or by substituting a conduit having an imperforate wall.

The form of this invention, hereinafter described, provides a valvecasing comprising a body portion, and a cap therefor in threadedengagement therewith and affording an enlargedequalizing chamber for theconvenient distribution of illuminant, said cap being supported bythreaded engagement with the supply pipe and suspending the body portionof said valve, which provides a downwardly tapering seat for the valveplug, a plurality of radially extending threaded sockets for the gasconduits communicating with said chamber through -said tapering valveseat, a hollow valve plug Ahaving ports arranged to register with saidconduits, said conduits being provided with `separate passages extendinglongitudinally therethrough, and connected with said chamber bypassageways extending through said valve body to convey illuminantindependplug, a sleeve threaded on said stem and secured thereto, a keythreaded in said sleeve `in ammed relation with said stem, and meanswithin said casing arranged to limit the movement of said valve.

This invention further includes the various novel features ofconstruction and arrangement as hereinafter more definitely specified.

In the drawings, Figure 1 is a central vertical sectional view of aconvenient form of this invention, certain of the parts being shown inelevation for convenience of illustration; Fig. 2 is a side elevation ofsaid valve; Fig. 3 is a horizontal sectional view of said valve taken onthe line 3 3 in Fig. 1; Fig. 4 is a central vertical sectional view of amodiiied form of valve taken on the line 4 4 in Fig. 5; and Fig. 5 is ahorizontal sectional view of the valve shown in Fig. 4 taken on the line.55 in said figure.

In the form of this invention shown in Figs. 1 to 3, inclusive, thevalve body 1 has the removable cap 2, forming the enlarged gagement withthe supply pipe 4. Said body 1 provides the threaded boss 5 forming t-heannular shoulder 6, arranged to support the gasket 7, against which theedge 8 of the cap 2 bears when assembled in engagement with the threadsof the boss 5, as shown in Fig. 1. y

The valve body 1 has the'downwardly tapering centrally disposed openingforming the valve seat 9, and a plurality ot' threaded sockets 10communicating through the ducts 11 with said opening and arranged toreceive the ends of the radially extending conduits 12 or 13, leading torespective burners of any convenient type (not shown).

The inverted, truncated cone-shaped valve plug 14, having the threadedstem 15, is rotatably seated by gravity in the valve seat 9 and has thecentral bore 16 in communication with the chamber 3 and provided withthe ports 17 leading Jfrom said bore and arranged to register with theducts 11 in the valve body 1 to open the passagefor illuminant from thesupply pipe 4 to the burners ent of t-he valve plug, a stem for saidvalve i' chamber 3, suspended in screw-threaded enthrough the chamber 3,ports 17, ducts 11 and conduits 12 or 13. The rotary move* ment of thevalve plug 14 is effected by the key 20, comprising the grip ring 21 andthe shank 22 in threaded engagement with the sleeve 23, which is also inthreaded engagement with the valve stem 15 and secured thereto by thescrew 25 extending transversely through said stem and sleeve, as bestshown in Fig. 1. Said valve plug 14 is limited in its rotary movement bythe stop pins 26 and 27, arranged to alternately engage the respectiveopposite ends of the semiannular boss 30 extending upwardly from theupper surface of said valve body 1, in its respective open and closedpositions. The valve plug 14 is conveniently adjusted axially in itsseat 9 in the usual manner by the nuts 32 and 33 adjustably engaging thewasher 34, carried by the reduced extension 35 of said valve plug 14, asshown in Fig. 1.

The form of conduits 13, as best shown at the right-hand side of Fig. 1,includes the longitudinal partition 38 forming the Separate passageway39 arranged to convey illuminant to a pilot light adjacent to the burner(not shown), and said passageway communicates with the chamber 3,independent of the valve plug 14, through the by-pass ducts 40, whichextend through the valve body 1 and may be conveniently tappedtherethrough when said valve body 1 is sep arated from the cover 2, and,as may be observed, said ducts may then be readily cleaned of anyobstruction which may be accidentally lodged therein. However, it may benoted that, as shown at the left-hand side of lFig. 1, the by-pass ducts40 may be closed if desired by simply substituting for the conduit 13the pipe 12, having the imperforate wall as shown, whereby said pipe orconduit is wholly controlled by the valve plug 14 and the ducts 40 areclosed by said imperforate wall.

In the form of this invention illustrated in Figs. 4 and 5, the valvebody 45 is provided with separate screw threaded sockets 46 and 47,respectively, for the main illuminant conduits 48 and by-pass ducts 50,which extend radially inwardly and then upwardly in communication withthe chamber 3. In other respects the form shown in Figs. 4 and 5 isidentical with the form illustrated in Figs. 1 to 3, inclusive.
